ABSTRACT:
A conveying apparatus for conveying tree trunks through a measuring device is disclosed in which the conveying apparatus comprises at least one transport chain and a plurality of drivers for receiving the tree trunks which are driven by the chain and slide on a guide track. A reliable supporting of the tree trunks on the drivers during transport through the measuring device is achieved which also prevents tilting of the tree trunks by providing drivers which are spaced apart in the conveying direction of the chain. Additionally, the engaging faces of the drivers are designed for receiving the tree trunks and extend perpendicularly to the conveying direction of the chain and are inclined where at least two drivers have oppositely extending inclines in the conveying region.
